Explanation:

[The Psychologist] was in the midst of his exposition when the door from the corridor opened slowly and without noise. I was facing the door, and saw it first. "Hallo!" I said. "At last!" And the door opened wider, and the Time Traveller stood before us. I gave a cry of surprise. "Good heavens! man, what's the matter?" cried the Medical Man, who saw him next. And the whole tableful turned towards the door.

He was in an amazing plight. His coat was dusty and dirty, and smeared with green down the sleeves; his hair disordered, and as it seemed to me greyer—either with dust and dirt or because its colour had actually faded. His face was ghastly pale; his chin had a brown cut on it—a cut half healed; his expression was haggard and drawn, as by intense suffering. For a moment he hesitated in the doorway, as if he had been dazzled by the light. Then he came into the room. He walked with just such a limp as I have seen in footsore tramps. We stared at him in silence, expecting him to speak.

He said not a word, but came painfully to the table, and made a motion towards the wine. The Editor filled a glass of champagne, and pushed it towards him. He drained it, and it seemed to do him good: for he looked round the table, and the ghost of his old smile flickered across his face. "What on earth have you been up to, man?" said the Doctor. The Time Traveller did not seem to hear. "Don't let me disturb you," he said, with a certain faltering articulation. "I'm all right." He stopped, held out his glass for more, and took it off at a draught. "That's good," he said. His eyes grew brighter, and a faint colour came into his cheeks. His glance flickered over our faces with a certain dull approval, and then went round the warm and comfortable room. Then he spoke again, still as it were feeling his way among his words. "I'm going to wash and dress, and then I'll come down and explain things … Save me some of that mutton. I'm starving for a bit of meat.'
